may experience different degrees of ordering of the B cations that can be varied by suitable synthesis conditions or post-synthesis treatment. In this work the earlier proposed statistical model of order-disorder phase transitions of B cations is extended to account for the effect of pressure. Depending on the composi…
High-entropy alloys are characterized by high configurational entropy. Since the discovery of high-entropy alloys (HEA) in 2004, entropy engineering has provided a promising direction for exploiting composition, lattice disorder, band structure, and microstructure effects to advance thermoelectric performance. This re…
Neutron reflectometry is a method for measuring of the spatial dependence (profile) of the potential interaction between neutron and medium. At interface of media the interaction potential is the sum of the elements potentials. For definition of potentials of separate elements (isotopes) a secondary radiation is recor…
Tissue-like materials are required in many robotic systems to improve human-machine interactions. However, the mechanical properties of living tissues are difficult to replicate. Synthetic materials are not usually capable of simultaneously displaying the behaviors of the cellular ensemble and the extracellular matrix…
Three new post-synthetic modification reactions, namely amidation, esterification, and thioesterification, were demonstrated on a novel highly crystalline two-dimensional covalent organic framework (COF), COF-616, bearing pre-installed carboxyl groups. The strategy can be used to introduce a large variety of functiona…
Abstract The goal of this study was to synthesize nickel oxide nanoparticles (NiO‐NPs) by the sol–gel method, which involved the use of salvia macrosiphon Boiss plant extract, Ni(NO 3 ) 2 ·6H 2 O as a capping agent, and a nickel precursor, respectively. The synthesized NiO‐NPs were characterized by Fourier transform i…
The wide commercialization of consumer products containing titanium dioxide nanomaterials (TiO2 NMs) contributes to a substantial increase of human exposure to this compound, which is worrying for public health, since the existent studies generated contradictory results about TiO2 safety. The oral exposure may occur e…
The mechanisms for forming experimentally observed nanoscale skyrmions in the absence of magnetic field or/and in the centrosymmetric systems are not yet known. By introducing biquadratic antiferromagnetic together with usual bilinear ferromagnetic nearest neighbor exchange interaction in a square lattice, we find tha…
Graphene was introduced into Li–N2 batteries to investigate the cycling stability, as described by Z. Zhang, Z. Zhou, and co-workers in their Research Article on page 17782 ff. The low efficiency and irreversibility of Li-N2 batteries are due to the instability and hygroscopicity of the discharge product Li3N. Moreove…
Carbon is one of the most abundant elements on earth. It is a versatile element that possesses a number of hybridisation modes to render an extensive range of allotropes. The carbon chemistry, at the nanoscale, is even more interesting to researchers not only because of improved physical properties, but also because i…
A utilização do equipamento de Usinagem por Fluxo Abrasivo (AFM) e desenvolvimento de pasta abrasiva utilizando óleo de oiticica, apresentam-se como uma necessidade diante dos problemas referentes ao processo de acabamento superficial de peças com pastas já existentes. O acabamento e polimento adequado da superfície,…
A partir de calculos de estructura electronica se estudio la anisotropia, y otras propiedades derivadas de esta, de compuestos magneticos mononucleares con espin 1/2. En los tres primeros capitulos la tesis se centra en el estudio de compuestos de metales de transicion. El primer capitulo relaciona la geometria y conf…
Colloidal semiconducting nanocrystals hold significant potential for third generation photovoltaics as solution processable materials that can surpass the Shockley-Queisser limit through multiexciton generation. In pursuit of this goal, the synthesis and optical characterization of CdSe/PbS core/shell quantum dots is…
Multiple myeloma (MM) is a hematologic malignancy of the antibody-producing plasma cells in the bone marrow. Most patients with MM respond to initial treatments, but nearly all will eventually relapse and die from this progressive disease. Although the mechanisms of cancer proliferation and resistance to conventional…
Eine neuartige feste Phase von fünfwertigem Plutonium wurde auf dem Reaktionspfad von wässrigem PuVI zu PuO2-Nanopartikeln beobachtet, wie K. O. Kvashnina et al. in ihrer Zuschrift auf S. 17722 berichten. Erreicht wurde dies durch die Kombination aus einer Fluoreszenzdetektion mit hoher Energieauflösung an den M4- und…
The dataset includes magnetic inversion results and high-resolution magnetic scan data of a 30µm thick section of a sample from Modum, Norway. The sample contains large magnetite grains (>100 µm) surrounded by serpentine and carbonate and exhibits a clear multi-domain behavior. Inversion of the data provided an estima…
Emerging nanocarbon materials like activated carbon, graphene, carbon nanotubes, etc. have reshaped the material science research field and offer an extensive range of diverse applications. This chapter covers different synthesis methods and characterisation techniques available to extensively study various physical a…
The objective of this thesis is to describe the study of cometary materials returned by NASA’s Stardust mission. The majority of the research presented in this thesis focuses on improving our characterization and understanding of the fine (< 1 µm) component of comet Wild 2. Investigations of the Stardust foils are con…
Hybrid energy technologies are the culmination of energy-harvesting and energy-storage systems that offer a new vista for replacing the age-old storage devices with self-powered units. They offer low maintenance as well as uninterrupted service life as compared to existing commercial storage solutions. Carbon plays a…
Kompozitni materijali su danas neizostavan dio suvremenog inženjerstva materijala, te kao takvi sve vise dobivaju na znacaju, upotrebi i razvoju naspram tradicionalnih konvencionalnih materijala. U ovom radu, opisane su vrste kompozitnih materijala s obzirom na razne vrste ojacanja i obzirom na razne vrste matrice. Na…
